While it may seem excessive to have to bring the auger out every few minutes, you will find you will actually drill the hole quicker and be more efficient with your wearparts.
By lifting the auger out of the hole, it allows the air back down the hole. When you are drilling for an extended period of time, the air is expelled from the drill face and it creates an oven effect at the bottom of the hole from the heat of the drill against the rock; the face of the rock you are attempting to drill will glaze over, (like it has been polished) and become a harder surface.
By lifting the auger out of the hole it allows air back down, cools the teeth tips and also allows you to check the teeth and replace if necessary – they are after all wearparts….
We commonly hear of people adding water to the hole, but this alone is not the answer. The frequency of removing the auger from the drill face has a much greater benefit. When drilling rock a small amount of water will certainly help to bind up the spoil, clear the head easier and help cool the teeth down but as we all know, water is not always readily available, especially on remote worksites.
#dnacontractservices have the right idea ... adding water while #drilling can help suppress dust and bind the spoil so it's easier to remove it all from the hole. Adding water is also useful when drilling in rock. It helps cool down the rock and the teeth on your #auger so that your wearparts last longer and the rock doesn't glaze over making it hard to drill #Digga #augerdrive #screwpiles #ScrewPiling #construction #australianmade #AustralianManufacturing
